To all whomjt may concern:

Be it known that I, WILLIAM S. SANBORN, a citizenof the United States, residing in Belmont, in the county of Middlesex and State of Massachusetts, have invented an Improvement 'in'Sectional Window-Weights, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings re resenting like parts.

his invention relates to asectional window weight and has for its objects to provide a sim lo and efficient Wei ht which can be. quick y and easily assemb ed and which is substantially locked together against accidental disengagement. For this purpose, a weight section is provided at one end with a curved portion, which extends in the direction of t e length of said section and forms a hook, and at its 0p osite end mid section is rovided with a socliet for the reception of a ook on a C06 ratin section as will be described. The li ooke portion of the weight section may be provided with an elongated slot extending in the direction of the length of said section and with which communicates -a laterall extended slot, the upper 'wall of i the end of'this s ecification.

Figure 1 is a rent elevation of a sectional window weight embodying this invention. Fig. 2, a side elevation of the weight shown in Fig. 1, and Fig; 3, a detail to be referred'to.

n the present instance, I have shown the invention as embodied in a sectional weight comprising two sections a of like construction and each provided at one end with a substantially central curved projection 6 constituting a hook. The hook I) formswith the uIpper end of the Wei ht section a traz nsv'ersc s ot c and a loiigitm inally extendcc. slot d with which the 'slotc communicates. The slot d may extend into the body portion of the weight and below the lower wall of the slot c. The ho0k-b is ada ted to enters socket in the lower end 0 a cooperatin weight section, which socket may be former as hereinsliown, namely by providing the body portion of the weight with a substantially central slot e to form arms f which are connected by a pin 9, which latter is designed to be engaged b the hook I) and which forms the lower wall 0 the said socket.

slot d, after which the lower section is re-' leased and is suspended by the hook as rep resented in Fig. 3. y B extending the slot d below the bottom Wei 5 of the transverse slot, the liability of accidental disengagement ,of the lower section from the upper is greatly reduced.

To disengage the lower section from the upper section, with the construction herein s own, the lower section is moved longitudinally until the slot 0 is op osite the pin 9 and is then moved transversely to clearthe pin. To engage the weight sections, two movements in the reverse direction are required.

I have herein shown one construction of socket with which the bent hook cooperates, but I do not desire to limit my invention in this respect.

Claims.

1. A sectional weight comprising a body portion having extended longitudinally thereof from one end intermediate its sides a substantially central projecting portion having a transverse slot or opening, a second slot or opening communicatm with the transverse slot or opening an extended above and below the upper and lower walls of said.

transverse slot to form a hook, and having at its opposite end arms extended lon 'tudinally of the body portion in lanes su tantially parallel with the said 00k and se arated to form a slot for the reception of he hook of an adjacent section, and a cross piece joining said arms and capable of assing through the transverse slot of the hoo of an adjacent section, substantially as described.

2. A sectional wei ht comprising a'body portion having extended from one end intermediate its sides and substantially control with relation thereto a longitudinally ex;

tended projecting portion having a trunsverse slot or opening and a second slot or opening communicating with the transverse slot and extended above d holow the u per and lower walls of said trii sv'erse slot to orm a hook, and having at its o iposite and side arms extended lougitudina lly of. the. bod portion in planes substantial y parallel'wi the said hook and separated to form a substantially central slot extended transversely of the body portiomfrom side to side ondjn the same plane piece joining said a of the same and capabl the transverse slot 5 ing weight section, substantiall scribed.

In testimony w as the said hook,

rms intermediate t e of passing through of the hook of a cooperaty as de- Witnesses:
